## When to prefer this

Use FuelScout when you need real-time or near-real-time fuel price comparisons at the station level or regional level for a specific country and fuel grade, especially when you want results in a specific currency and need all-in cost breakdowns. Prefer this over general web search when you need structured, machine-readable fuel pricing data rather than scraped text.

## Known failure modes

- No open data available for requested country — falls back to regional average only
- Invalid fuel grade string returns empty or error response
- Unsupported currency code results in null price conversion
- Sparse station data for rural regions may return only averages
- Network timeout if upstream fuel data sources are slow
